[jsword-devel] webstart

Fri Sep 3 12:05:16 MST 2004

I've figured out that the jpx are JBuilder project files. So I 
downloaded the free Personal version and loaded the project into it.

Is this an appropriate version of JBuilder? So far I am poking around 
trying to figure out how the IDE works and how the app is maintained 
w/in it. (The code is easy to figure out.)

Still wondering if you used a GUI builder. If so, is it a part of 
Personal ver and how do you invoke it?
